Later Diego de Villarreal purchased a
silver mine from his wife's sister Juliana. The Hacienda de
Chipinque, today the Villa of Carmen, Nuevo Leon, this
property was inherited by dona Juliana de las Casas, who
also inherited her father's encomienda of the Cacuilipalina
Indians. Diego de Villarreal is credited for founding the
town of El Carmen Nuevo Leon.

On the 30th of June 1687 Diegos sons
presented themselves before Sr. Agustin Echevers y Subisar,
Marques de San Miguel de Aguayo, Caballero de la Orden de
Santiago, Vizconde de Santa Olaya, Gobernador y Capitan
General del Nuevo Reyno de Leon, to present to him Diegos
holdings and to divide his assets as their
inheritance.
